parameter for water soluble “adsorbable organic halogens” in which ‘A’ stands for adsorbable, ‘O’ for organic and ‘X’ for the halogens chlorine, bromine and iodine. After the introduction of the AOX in 1976, this parameter has been correctly used for “real” AOX constituents (DDT and its metabolites, PCBs, etc.); but also misused for non-adsorbable adsorbed OX-compounds, mostly high molecular organohalogens in plants and even to inorganic compounds being neither organic nor adsorbable. The question of
What are organic compounds, you may ask? Well organic compounds are compounds that always contain carbon, or any compound that contains a carbon atom. But some describe organic compounds as any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly are hydrogen, oxygen, and nitrogen. But there are a few exceptions to this organic rule, which are carbon monoxide, carbonates, carbon dioxide, cyanides, cyanates, carbides
Compounds are materials made from two or more than two elements through a chemical bond. In each compound elements are arranged in a definite shape hence changing their properties from the element. Every compound possesses its own different properties such as weight, melting point, freezing point etc. Types of Compounds: There are two types of important compounds. 1) Ionic Compound: These are the compounds that possess an electric charge in them and are
Diphenyl ether, first gaining attention in the late nineteenth and early twentieth century, is an organic compound that belongs to the ether organic functional group with a molecular formula of C12H10O. Also referred to as 1,1’-Oxybisbenzene, biphenyl oxide, diphenyl oxide, phenyl oxide, phenyl ether, or phenoxybenzene, diphenyl ether consists of two phenyl rings attached by an oxygen atom. The structural formula appears in Figure 1. Phenyl rings, C6H5, are extremely similar to benzene rings, C6H6

Organic compounds are commonly found every day in every part of life. Propionaldehyde is a common organic compound also known as propanal, propaldehyde, and methylacetaldehyde with propanal being the most common alternate name. It is a clear colorless liquid at room temperature. Coming from the functional group of aldehyde, propionaldehyde has a C=O bond in replace with two hydrogen atoms, which would be the base propane molecule. The molecular formula is C3H6O, the structural formula CH3CH2CHO,
The vastness of space holds many mysteries. One such mystery has puzzled scientists for hundreds of years; that of the abiogenesis of life. Exactly how can such complex organic structures blossom from nothing more than large chunks of elementally simplistic rock? On June 30th, 1908, another of these universal mysteries (although one that can be considered philosophically smaller) released 10-15 megatons of energy in a blast that devastated large swathes of the Tunguska forest region in Russia. Many
beautifully simple, consisting of one carbon atom to which four hydrogen atoms have become attached,”(19). Carson’s words explain the organic compound she is discussing, not only does she describe the compound, Rachel also presents a diagram of the compound for reader’s who are not as knowledgeable in the subject. The diagrams presented branch out into different organic compounds such as: methyl chloride, and anesthetic chloroform.Through this strategy, readers are able to enjoy the material being presented
Structure and Function of Lipids in Plants and Animals Lipids are the name given to a mixed group of organic compounds. The elements Hydrogen, Oxygen and Carbon are always found in Lipids. The difference between them and Carbohydrates is that they have a lower proportion of Oxygen in the molecule. Lipids are insoluble in water, but they are soluble in organic solvents, such as ether, acetone, chloroform or benzene. There are several parts in the group of Lipids: o fats and oils,
Proteins Proteins are the macromolecules of life. Discovered in 1838, proteins are recognized as a large number of superior organic compounds that make up living organisms and are essential to their functioning. The term protein comes from the Greek word “proteies” or “primary”. Proteins have many different properties and function in a variety of ways. They can function as a building material, in teeth, bones and muscles, and they can serve as enzymes, hormones, and neurotransmitters. Its functions
Isolation of a Urea Degrading Bacteria Introduction Urea was the first organic chemical to be synthetically produced1, previously it was thought that only living creatures could produce organic compounds Urea is naturally produced by the kidneys as waste from the degradation of amino acids. It is because of this that urea is commonly found in soils and is a useful nutrient source for bacteria that are able to utilise it, such as, Helicobacter pylori, Klebsiella pneumonia, all species of Proteus
the chamber ionizes (i.e. becoming a plasma) when the voltage hits the striking voltage and starts conducting electricity, causing it to glow. The color depends on the gas used. The RFGD treatment involves the removal of impurities and weakly bound organic contamination from surfaces through the use of the energetic plasma created from gaseous species. The device is connected to a vacuum to remove all atmospheric contaminants and debris produced throughout the process. RFGD can treat a wide-range of
bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the
Mercury: A toxic poison No other metal better illustrates the diversity of effects caused by different chemical species than does mercury. On the basis of chemical speciation, there are three forms of mercury: elemental, inorganic, and organic compounds. The major source of mercury is the natural degassing of the earth's crust, including land areas, rivers, and the ocean, and this source is estimated to produce on the order of 2700 to 6000 tons per year. The total man made release into the
smog. However, the burning of fossil fuels like gasoline can create another atmospheric pollution problem known as photochemical smog. Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different and hazardous chemicals known as secondary pollutants. Development of photochemical smog is typically associated with
break down organic molecules and release the nutrients back into the soil[2]. However, in a farm, the plants (i.e. crops) are harvested and the nutrients are removed with them. If a high yield is to be maintained for a number of years the nutrients must be replaced. Therefore in order to maintain productivity in agriculture farmers need to use fertilisers containing these nutrients. There are two types of fertilisers used by farmers in agriculture: inorganic fertilisers and organic fertilisers

Before her lover has a chance to speak he is suspect because "porphyria," as defined by Reader’s Digest Illustrated Encyclopedia Dictionary is: A hereditary disease involving disturbance in the metabolism of porphyrins [organic compounds that provide the foundation structure for blood in animal tissues] and producing symptoms of mental confusion, neuritis, and abdominal pain. (1319) The title suggests that Porphyria’s lover is not even revealing the name of the woman he strangles
To uncover organic compounds like carbohydrates, lipids, proteins and nucleic acid, by using tests like Benedict, Lugol, Biuret and Beta Carotene. Each test was used to determine the presents of different organic molecules in substances. The substances that were tested for in each unknown sample were sugars, starches, fats, and oils. Moreover, carbohydrates are divided into two categories, simple and complex sugars. Additionally, for nonreducing sugars, according to Stanley R. Benedict, the bond
Everything You Need to Know about Vitamins Vitamin, any of the organic compounds required by the body in small amounts for metabolism, to protect health, and for proper growth in children. Vitamins also assist in the formation of hormones, blood cells, nervous-system chemicals, and genetic material. The various vitamins are not chemically related, and most differ in their physiological actions. They generally act as catalysts, combining with proteins to create metabolically active enzymes that
Fractional Distillation of Crude Oil BOILING POINTS AND STRUCTURES OF HYDROCARBONS The boiling points of organic compounds can give important clues to other physical properties. A liquid boils when its vapor pressure is equal to the atmospheric pressure. Vapor pressure is determined by the kinetic energy of molecules. Kinetic energy is related to temperature and the mass and velocity of the molecules. When the temperature reaches the boiling point, the average kinetic energy of the liquid particles
